Patented Oct. 22, 1929 UNITED CHARLES L. HUNT AND NETTER J'. HILL, OFST. LOUIS, MISSOURI, .FASSIGNORS TO NON- REFILLABLE CONTAINER, INC., OFST. LOUIS, MO., A. CORPORATION 0F MISSOURI` LIQUID CONTANER Applicationmea July 11,

improved valve device for use in connection with liquid containers'comprising a pipe eX- tending through the top of the container to-`ward the bottom and having its lower end open and equipped with meansfor supporting a valve seat, in combination with a support equippedYwith a valve seat and a valve and means for removably supporting thesupport and thereby the valve within said pipe.

:Another object ofthe invention is to provide a device for replacing andremoving said support from the pipe. l l

Other objects will appear from the following descriptiom'reference beingmade to the drawing in which .f l A Y Fig. 1 is a view .showing aVcontainer equipped with thepresent invention.

'Figi 2 is an enlarged vertical sectional view of the invention.

Figs. 3 and 4 are cross sectional views on the lines 3-3 and 4 4,respectively, of Fig. 2.

Fig. 5 is a sectional view ','howing adevice for inserting and removingthe valve support from the pipe through which the container is filledand emptied. Y

The container in which the invention is shown is a barrel of familiarconstruction comprising a shell 1, a top wall 2 and a bottom wall 3. 1

A pipe 4 extends through a hole in the top 2 -to the bottom 3. Animpervious joint beiy tween the top wall 2 and theupper end ofthe pipe 4may be obtained by a ring of solder 5 applied at the joint. The lowerend of the pipe 4 has a number of notches 6 so as to permit the liquidcontents of the container to be withdrawn through the pipe 4 or topermit the container to be refilled. The inside of the pipe 4 at itsupper end is threaded and is closed by a removable plug 7 duringshipment or when the container is in storage.

1928. Serial No. 291,718.

'This plug'm'ay'be removed and the usual4 threaded attachment of a pump(not shown)v may be screwed in place of the plug to withy l draw theliquid contents of the container.

A'sleeve 8 is secured within thelower end of the `pipe 4 above thenotches 6. This sleeve is not rotative within the pipe. A cotter pin 9extends diametricallythrough the lower ends of the pipe'4 and the sleeve8 and, if desired, this cotter pin may function to support and hold vthesleeve 8 from rotation in the pipe. Or, the sleeve may be otherwise heldis internally` from rotation. The sleeve 8 threaded atits upper end. Y

A Vtubular valve support 10 is exteriorlyI threaded at its upper end andis insertable in the sleeve 8 until the threads on the outuntil thelower end'of said support abutsVV against the Cotter pin v9 and preventsfurther rotation of `said support 10 in the direction v in which it mustbe rotated screwed into the sleeve 8. j Some distance below its upperend the supwhen'it is ybeing the support 10 has a valve stem guide 13.A' valve stem 14 extends throughthe guide 13 and on its upper end isequipped with a Valve l port 10 is formed with'a valve seat 11 having fan opening 12; and below the valve seat 11,

15 movable to and from the seat 11 to close and toopen the opening 12. YThe valve stem 14 has a nut 16 screwed on its lower end below` the guide13 and this nut serves to limit move- 'Y ment of the valve 15 towardopen position.

The device for inserting and withdrawing the valve device is shown inFig. 5, the same comprising a rod 17 having a plug 18 atto be screwedinto engagement with threads 19 on the inside of the upper end of thesupport 10 Iabove the valve seat 11. These threads 19 are formedoppositely from ythe threads on the outside of the support '10 so thatvthere will be no difficulty in using the device '17-18 to vinsert andto remove the support 10. Lugs 2O at the lower end of the threads 19constitute abutments for the'plug tached to one end and designed Vandadapted 18 to prevent the same from being screwed so far into thesupport 10 as to become rigid. The rod 17 has one or more discs 21functioning as guides when inserted within the pipe 4 so as to hold therod 17 aXially within the pipe. A handle 22 is in connection with theupper end of the rod 17.

Initially the container 1 is filled with oil or other liquid through thepipe 4 before the valve support 1() is inserted, it being understoodthat the upper end wali 2 is provided with the usual vent (not shown).After the container 1 is `{illed the support 10 screwed on the plug 18is passed downwardly through the pipe 4 until the threads on the outsideof the upper end of the support 10 engage the threads on the inside ofthe upper end of Vthe sleeve 8, When said threads are brought intoabutting contact the handleV 22 is operated to rotate the rod 17 andthereby the'plug 18 and the support 10 which is screwed on said plug.Suc-h rotationis in a direction necessary to screw the support 10 intothe sleeve 8 and continues until the lower end of thesupport lOvabutsagainst the cotter pin 9. Then continued rotation of theV plug 18 in thesame direction unscrews theY same from the support 10 and the plug,together with the rod '17, is withdrawn from the pipe 4. Then the plug 7is applied and kept in connection with the device so long as thecontainer is in shipment or in storage.

When it is desired to withdraw the liquid contents of the container theplug 7' is ref -moved and a pump is secured in connection with the upperend` of the pipe 4 in the saine way that the pump is usually attached tothe opening inthe top of an oil barrel. When the pump is operated thevalve 15 will, of course, be raised, permitting the liquid contents ofthe container to be pumped out. But, thefcontainer cannot be refilled solong as the valve support 10 remains in position in the pipe, for thevalve 15 prevents inflow of liquid. When it is desired to rell thecontai1ie1"t.he device 17e-'18 must be screwed into engagement with thethreads 19 and continuoilsly rotated until the support 10 is unscrewedfrom the sleeve 8. ihen the support 10 becomes disengaged from thethreads on the sleeve 8 the attaching and detaching tool may bewithdrawn and with it the support 10 will be withdrawn from the pipe 4.Then, it is apparent that the container may be refilled.

The construction, arrangement and relationship .of the parts may bevaried within equivalent limits without departure from the nature andprinciple of the invention. Y

We do not restrict ourselves in unessential respects, but` what we claimand desire to secure by Letters Patent is 1. In a container having upperand lower end walls, a pipe extending through one of said walls towardthe other, a valve support, a threaded element for supporting said valvesupport within the inner end of said pipe, an abutment for the inner endof said valve support, a valve seat in said valve support, a valvemovable to and from said seat, and means for guiding said valve.

2. .ln a liquid container having upper and lower end walls, a pipeextending from the upper end wall toward the lower end wall, internalscrew threads within the lower portion of said pipe, a cylindricalVvalve support, external screw threads on one end of said valve supportscrewed into said first-named screw threads, a valve supported withinsaid valve support, and a device for operating said valve support toscrew the saine in position and to unscrew the same for removal fromsaid pipe.

3. Tn a container having opposite end walls, i

a pipe exten-ding through one of said end walls toward the otherandhaving lateral openings at its inner end, a sleeve Isecured withinthe inner end of said pipe above said openings, a cylindrical valvevsupport relnov` ably supported in said sleeve, an abutment limitingextent of inward' movement of said valve support in said sleeve, and avalve supV porte'din said valve support. v Y

4. In a container having opposite end walls, a pipe extending throughone of` said i end walls towardy the other and having lateral openingsat its inner end, a sleeve `secured within the inner end of said pipe,above said openings, a cylindrical valve support remove vably supportedin said sleeve, an abutment limiting extent of inward movement of saidVvalve support in said sleeve, a valve supported in said valve support,and means in the outer end of said valve support outwardly beyond saidvalve for engaging with ,apositionin and removing tool. having upper andlower 5. In a container end walls, a pipe having its upper endopeningthrough one of said end walls and extending downwardly'toward the otherand ope-ning laterally into said container near said other end of saidcontainer, ,a cylindrical valve support of less diameterthan theinsideof said pipe betweenl said support and the upper end of said pipescrewed into said pipe near the end of said pipe which opens latere allyinto said container as aforesaid, means?,

limiting extent of movement of said valve support toward said other endof said container and preventing said valve support from closingcommunication from said pipe to said container, and a valve supportedwithin said valve support. p CHARLES L. HUNT. NETTER J. HILL.
